[Feature request] Reject input with invisible/zero-width character

[JoeyC-Dev]

Describe the solution you'd like For example, there is a yaml file as below, and it should be rejected:

apiVersion: secrets-store.csi.x-k8s.io/v1
kind: SecretProviderClass
metadata:
  name: azure-kvname-wi 
spec:
  provider: azure
  parameters:
    usePodIdentity: "false"
    clientID: 00000000-0000-0000-0000-000000000000​
    keyvaultName: ${KEYVAULT_NAME}
    cloudName: ""
    objects:  |
      array:
        - |
          objectName: secret1 
          objectType: secret 
          objectVersion: ""      
    tenantId: "${IDENTITY_TENANT}" 

When there is a root cause like this happening to an incident, it is a disaster to find it out.  (The reason I submitted this feature request is because it happened recently. We just had no where out at the time until we find the "space-like" thing when manually opened the yaml with VSC. The issue kept for 3 days.)
